I implemented the same thing but in a different way. I used a GridView
control to display a list of records, to which I added code in the
code behind to its OnRowDataBound event. The GridView control is bound
to a custom class that retrieves a record from the database. In the
aspx file you add:

<asp:GridView ID="applicationGrid"
OnRowDataBound="applicationGrid_OnRowDataBound".........</
asp:GridView>

Then in the code behind added the following:

        protected void applicationGrid_OnRowDataBound(object sender,
GridViewRowEventArgs e)
        {
            string url = "";
            Application newApp = e.Row.DataItem as Application;

            if (newApp != null)
            {
                if (e.Row.RowType == DataControlRowType.DataRow)
                {
                    url = "controller.aspx?edit=true&application_id="
+ newApp.ApplicationId + "&status=" + newApp.Status;
                    e.Row.Attributes["onclick"] =
"document.location.href='" + url + "'";
                    e.Row.Attributes.Add("onmouseover",
"this.style.cursor='pointer'");
                }
            }
        }

The GridViewRowEventArgs parameter corresponds to a record containing
the data for each case in the list. I create a new instance of this,
grab the values I need, then construct the url and add the url to the
onclick attribute of the row.

Hope this helps.

Ciaran.
